An FPU is not required as the 80default kernels include FP-emulation support. 81.It Hades 82A standard Hades with either an 040 or 060 processor and at least 8 Mb of RAM. 83.El 84.\" 85.\" 86.\" 87.Sh DEVICE SUPPORT 88This section describes the hardware supported on the atari 89(atari-clone) platform. 90Software support for these devices comes in two forms. A hardware 91device may be supported with a character or block 92.Em device driver , 93or it may be used within the networking subsystem and have a 94.Em network interface driver . 95Block and character devices are accessed through files in the file 96system of a special type; see 97.Xr mknod 8 . 98Network interfaces are indirectly accessed through the interprocess 99communication facilities provided by the system; see 100.Xr socket 2 . 101.Pp 102A hardware device is identified to the system at configuration time 103and the appropriate device or network interface driver is then compiled 104into the system. When the resultant system is booted, the 105autoconfiguration facilities in the system probe for the device 106and, if found, enable the software support for it. 107If a device does not respond at autoconfiguration 108time it is not accessible at any time afterwards. 109To enable a device which did not autoconfigure, 110the system must be rebooted. 111.Pp 112The autoconfiguration system is described in 113.Xr autoconf 4 . 114A list of the supported devices is given below. 115.Sh LIST OF DEVICES 116The devices listed below are supported in this incarnation of 117the system.
